ATI products are designed with the working site in mind, not just the lab. Each product installs simply and consistently, without complex detailing or improvised workarounds. The result is a repeatable process that doesn't slow the build program.

Independently tested and documented to support NCC compliance without the guesswork.

Available in multiple thicknesses to suit your current wall design or step up your Total Wall R-Value for stronger 7-Star outcomes.

ATI products are built to perform across the life of the building, not just at handover. Dimensional stability under load, tested R-values and compatibility with major cladding manufacturer guidance are built in from the start. That means fewer callbacks and greater confidence in the long-term outcome.
Each product in our range is independently tested, clearly documented and available through our stockist network.
